In some embodiments of the present invention, according to the foregoing, the adjustment of the area where the water absorbing member 4 actually contacts with the surface to be cleaned is realized by the friction force between the water absorbing member 4 and the surface to be cleaned, and on this basis, in order to ensure the effectiveness and reliability of the adjustment and avoid the problem of incapability of adjustment due to seizure or insufficient friction force, the cleaning device 100 further includes a driving assembly, the driving assembly is connected to the housing, and at least one of the first rotating member 1 and the second rotating member 2 is connected to the driving assembly. The arrangement mode of the driving assembly comprises the following conditions: the first rotating part 1 is connected with a driving assembly, the driving assembly is used for driving the first rotating part 1 to rotate, two ends of the water absorbing part 4 are respectively connected with the first rotating part 1 and the second rotating part 2 and wound on the second rotating part 2, and the water absorbing part 4 is released from the second rotating part 2 and gradually wound on the first rotating part 1 by means of the rotation of the first rotating part 1; secondly, the driving assembly is connected with the second rotating part 2 and is used for driving the second rotating part 2 to rotate, two ends of the water absorbing part 4 are respectively connected with the first rotating part 1 and the second rotating part 2 and wound on the first rotating part 1, and the water absorbing part 4 is released from the first rotating part 1 and gradually wound on the second rotating part 2 by means of the rotation of the second rotating part 2; and the third type is that the driving components are provided with two groups, namely a first driving component and a second driving component, the first driving component is connected with the first rotating component 1 to drive the first rotating component 1 to rotate, the second driving component is connected with the second rotating component 2 to drive the second rotating component 2 to rotate, the release and the rolling of the water absorbing component 4 are realized, and the repeated cleaning of the water stain on the cleaned surface by the water absorbing component 4 can be realized through the two groups of driving components.

Specifically, the rotating speed of the first driving assembly is greater than that of the second driving assembly for illustration, the water absorbing piece 4 is released from the second rotating piece 2 and gradually wound onto the first rotating piece 1, the winding speed is greater than the releasing speed due to the speed difference of the first driving assembly and the second driving assembly, the effect that the water absorbing piece 4 is tensioned is achieved, and the problem that the water stain cleaning effect is poor due to the fact that the water absorbing piece 4 is folded and stacked is avoided. In other embodiments, a tensioning member may be provided on the housing to keep the absorbent member 4 flat against bunching of the absorbent member 4 when the absorbent member 4 is in contact with the surface to be cleaned.

In other embodiments, the area of the water absorbing member 4 actually contacting with the surface to be cleaned can be adjusted by manual adjustment by setting a knob or the like, in addition to automatic adjustment by the driving component. The first rotating part 1 and the second rotating part 2 are both round shaft-shaped parts, in the cleaning process, the first rotating part 1 and the second rotating part 2 rotate around respective rotating axes, and the rotating axes of the first rotating part 1 and the second rotating part 2 are parallel to each other, so that the water absorbing part 4 can be uniformly released and uniformly wound in the releasing and winding processes, and the water absorbing part 4 is prevented from being folded and stacked.

In other embodiments, a line connecting the rotation axis of the first rotating member 1 and the rotation axis of the second rotating member 2 may be parallel to an acute angle with the surface to be cleaned or an obtuse angle with the surface to be cleaned, and an elastic member may be provided to adjust the contact area between the water absorbing member 4 and the surface to be cleaned and the distance between the housing and the surface to be cleaned. The different angles between the axis of rotation and the surface being cleaned can influence the area of contact between the piece 4 that absorbs water and the surface being cleaned, and then influence the cleaning effect and the clearance efficiency of water stain.

In some embodiments of the present invention, the rotation directions of the first rotating member 1 and the second rotating member 2 may be the same, and the water absorbing member 4 is wound on the first rotating member 1 and the second rotating member 2 in opposite directions, and the winding manner of the water absorbing member 4 on the first rotating member 1 and the second rotating member 2 includes the following cases: the water absorbing member 4 of the first type passes through the lower part of the first rotating member 1, passes through the lower parts of the first rotating member 1 and the second rotating member 2, finally passes through the lower part of the second rotating member 2 and is wound on the second rotating member 2, in this case, the water absorbing member 4 contacting with the surface to be cleaned is a part between the first rotating member 1 and the second rotating member 2, and the water absorbing member 4 contacts with the surface to be cleaned in a surface contact manner; in the second type, the water absorbing member 4 passes through the first rotating member 1, passes through the first rotating member 1 and the second rotating member 2, and finally passes through the second rotating member 2 and is wound on the second rotating member 2, in this case, the water absorbing member 4 contacting the surface to be cleaned is the lowest point wound on the first rotating member 1 and the second rotating member 2, and the water absorbing member 4 is in line contact with the surface to be cleaned. The rotating directions of the first rotating member 1 and the second rotating member 2 are opposite, one is clockwise rotation, the other is counterclockwise rotation, the winding directions of the water absorbing member 4 on the first rotating member 1 and the second rotating member 2 are the same, and the winding modes of the water absorbing member 4 on the first rotating member 1 and the second rotating member 2 include the following conditions: the water absorbing piece 4 of the first type penetrates out from the lower part of the first rotating piece 1, passes through the middle of the first rotating piece 1 and the second rotating piece 2, finally penetrates out from the upper part of the second rotating piece 2 and is wound on the second rotating piece 2, in this case, the water absorbing piece 4 contacting with the surface to be cleaned is the lowest point wound on the first rotating piece 1 and the second rotating piece 2, and the water absorbing piece 4 is in line contact with the surface to be cleaned; in the second type, the water absorbing member 4 passes through the upper part of the first rotating member 1, passes through the middle of the first rotating member 1 and the second rotating member 2, and finally passes through the lower part of the second rotating member 2 to be wound on the second rotating member 2, in this case, the water absorbing member 4 contacting with the surface to be cleaned is the lowest point wound on the first rotating member 1 and the second rotating member 2, and the water absorbing member 4 is in line contact with the surface to be cleaned. As shown in fig. 1 to 12, in one embodiment, the first rotating member 1 and the second rotating member 2 rotate clockwise or counterclockwise, and the water absorbing member 4 penetrates from below the first rotating member 1, passes through below the first rotating member 1 and the second rotating member 2, and finally penetrates from below the second rotating member 2 to be wound on the second rotating member 2, in this case, the water absorbing member 4 contacting with the surface to be cleaned is a portion between the first rotating member 1 and the second rotating member 2, and the water absorbing member 4 contacts with the surface to be cleaned in a surface contact manner.

In some embodiments of the present invention, the water absorbing member 4 contacting the surface to be cleaned is a portion between the first rotating member 1 and the second rotating member 2, and the contact area of the water absorbing member 4 and the surface to be cleaned is positively correlated to some extent with the water spot cleaning ability and the cleaning efficiency, and the contact area is also dependent on the distance between the first rotating member 1 and the second rotating member 2 in addition to the tension degree of the water absorbing member 4. The distance between the first rotating member 1 and the second rotating member 2 also determines the volume of the cleaning apparatus 100.

In some embodiments of the present invention, the absorbent member 4 has water absorbing properties and can be released and rolled, the absorbent member 4 is required to have a soft texture, and the absorbent member 4 may be a pure cotton material, a sponge material or a fiber material.

In some embodiments of the present invention, since the water absorbing member 4 is soft in texture, a problem of partial stacking of the water absorbing member 4 is easily occurred, and a support member 5 may be provided in addition to tensioning of the water absorbing member 4 by setting a difference in the rotation speed of the first rotating member 1 and the second rotating member 2, the support member 5 being attached to the housing. According to the foregoing, the water absorbing member 4 passes through the lower portion of the first rotating member 1, passes through the lower portion of the first rotating member 1 and the second rotating member 2, and finally passes through the lower portion of the second rotating member 2 and is wound on the second rotating member 2, so that, in order to ensure the surface contact and balance between the water absorbing member 4 and the surface to be cleaned, the support member 5 is disposed in the space formed by the first rotating member 1, the second rotating member 2 and the water absorbing member 4, that is, the support member 5 is disposed on the side of the water absorbing member 4 away from the surface to be cleaned, the support member 5 supports the water absorbing member 4 disposed between the first rotating member 1 and the second rotating member 2, the effectiveness of the contact between the water absorbing member 4 and the surface to be cleaned is increased as much as possible, the contact area between the water absorbing member 4 and the surface to be cleaned is not reduced by the disposition of the support member 5, and the cleaning capability and the cleaning efficiency of the water absorbing member 4 for water stains are improved, to reduce deformation and stacking of the absorbent member 4 when in contact with a surface to be cleaned. The frictional force between the supporting component 5 and the water absorbing part 4 can also play the effect of tensioning the water absorbing part 4, and the problem that the water stain cleaning effect is poor due to the fact that the water absorbing part 4 is folded and stacked is avoided.

Wherein the contact area between the supporting component 5 and the surface to be cleaned or the area of the water absorbing member 4 between the first rotating member 1 and the second rotating member 2 which are supported up is in positive correlation with the contact effectiveness between the water absorbing member 4 and the surface to be cleaned to a certain extent. The position of the water absorbing member 4 between the first rotating member 1 and the second rotating member 2, the position of the first rotating member 1, and the position of the second rotating member 2 in a direction perpendicular to the surface to be cleaned may be the same as or different from each other.

In some embodiments of the invention, the support assembly 5 comprises at least one support. As shown in fig. 5 to 7, when the supporting member is a single member, the supporting member is a flat plate, and the supporting member is fixedly connected to the housing. The water absorbing member 4 penetrates out from the lower part of the first rotating member 1, passes through the lower part of the supporting member, and finally penetrates out from the lower part of the second rotating member 2 to be wound on the second rotating member 2. The width of the supporting piece can be larger than, equal to or smaller than the distance between the first rotating piece 1 and the second rotating piece 2, so that the cross section formed by the water absorbing piece 4, the first rotating piece 1, the second rotating piece 2 and the flat supporting piece is trapezoidal or rectangular, two sides of the flat supporting piece are arranged to be arc-shaped, and the water absorbing piece 4 is prevented from being abraded by the sharp part of the supporting piece.

In some embodiments of the present invention, as shown in fig. 8 to 9, when the supporting member is a single member, the supporting member is a circular shaft-shaped member, and can be fixedly connected to the housing or can be rotatably connected to the housing. The water absorbing member 4 penetrates out from the lower part of the first rotating member 1, passes through the lower part of the supporting member, and finally penetrates out from the lower part of the second rotating member 2 to be wound on the second rotating member 2. The first rotating member 1 or the second rotating member 2 and the supporting member are at the same position in the direction perpendicular to the surface to be cleaned, the water absorbing member 4 is supported by the first rotating member 1 or the second rotating member 2 and the supporting member to make the water absorbing member 4 contact with the surface to be cleaned in a surface contact manner, and the cross section formed by the water absorbing member 4, the first rotating member 1, the second rotating member 2 and the round shaft-shaped supporting member is triangular.

In some embodiments of the present invention, when there are two supporting members, the positions of the first rotating member 1 or the second rotating member 2 and the two supporting members in the direction perpendicular to the surface to be cleaned may be the same or different. In one embodiment, the line connecting the rotation axis of the first rotating member 1 and the rotation axis of the second rotating member 2 is parallel to the surface to be cleaned, as shown in fig. 10 to 12, the support assembly 5 includes a first support member 51 and a second support member 52, the first support member 51 is connected to the housing and located below the first rotating member 1, the second support member 52 is connected to the housing and located below the second rotating member 2, and further, the rotation axes of the two support members, the rotation axes of the first support member 51 and the second support member 52 are parallel to each other and the line is parallel to the surface to be cleaned.

The first support 51 and the second support 52 are both circular shaft-shaped parts, and the water absorbing member 4 moves along the circular arc surfaces of the first support 51 and the second support 52, so that the water absorbing member 4 is prevented from being worn at the sharp positions of the first support 51 and the second support 52. Further, in order to reduce the friction between the water absorbing member 4 and the first and

second supports

51 and 52, the first and

second supports

51 and 52 are configured to be rotatably coupled to the housing, and the sliding friction is converted into rolling friction, thereby further reducing the friction between the water absorbing member 4 and the first and

second supports

51 and 52.

In some embodiments of the present invention, according to the foregoing, the area where the water absorbing member 4 actually contacts the surface to be cleaned is adjusted by releasing and winding up the water absorbing member 4 through the rotation of the first rotating member 1 and the second rotating member 2 driven by the driving assembly, and the driving assembly can make the first rotating member 1 and the second rotating member 2 rotate continuously, for example, at a constant speed or at a variable speed, or can make the first rotating member 1 and the second rotating member 2 rotate intermittently. When the first rotating member 1 and the second rotating member 2 are continuously rotated, the rotating speed is preset to match the cleaning speed of the cleaning device 100, so as to avoid that the water absorbing member 4 is adjusted when not reaching the saturation state and is not adjusted when reaching the saturation state. When the first rotating member 1 and the second rotating member 2 are intermittently rotated, the rotation duration and the non-rotation duration are preset to match the speed at which the cleaning device 100 performs cleaning, so as to prevent the water absorbing member 4 from being adjusted when it has not yet reached the saturated state and from being adjusted when it has not yet reached the saturated state. The above is open-loop control of the operation of the drive assembly, and the degree of open-loop control is set simply.

In some embodiments of the present invention, instead of open-loop control of the drive assembly, closed-loop control may be provided, which may be more precise. As shown in fig. 10 to 12, the humidity value of the area where the water absorbing member 4 actually contacts the surface to be cleaned is detected in real time by providing the humidity sensor 6, and a preset humidity value is set as a criterion whether to adjust the area where the water absorbing member 4 actually contacts the surface to be cleaned. A moisture sensor 6 is attached to the housing on the side of the absorbent member 4 remote from the surface to be cleaned. A controller is arranged between the driving component and the humidity sensor 6, and the receiving of signals and the transmission of signals are realized through the controller. When the humidity value detected by the humidity sensor 6 is smaller than the preset value, the signal is sent to the controller, and the controller controls the driving assembly not to act, namely the water absorbing piece 4 keeps the current state to continuously clean water stains; when the humidity value detected by the humidity sensor 6 is larger than or equal to the preset value, the signal is sent to the controller, and the controller controls the driving assembly to act, so that the first rotating piece 1 and the second rotating piece 2 realize the release and the rolling of the water absorbing piece 4, and the adjustment of the area of the water absorbing piece 4 actually contacted with the surface to be cleaned is realized.

The humidity sensor uses the shell as a mounting point, and the humidity sensor and the water absorbing piece 4 can be in contact with each other or not in contact with each other.

In some embodiments of the present invention, in other embodiments, a coil spring may be disposed on a side of the absorbent member 4 away from the surface to be cleaned or inside the absorbent member 4, and the length of the coil spring is the same as that of the absorbent member 4.

The embodiment of the present invention further provides a cleaning apparatus 200, which includes the cleaning device 100 in any of the above embodiments.

The cleaning device 200 of the embodiment of the invention has the same advantages as the cleaning apparatus 100 of the above embodiment, and is not described herein again. In one embodiment, the cleaning apparatus 200 is a handheld mopping machine or a mopping robot. The cleaning device 200 also includes a cleaning tank, auxiliary wheels, drive wheels, and the like. The cleaning box can be used for containing cleaning liquid, and the cleaning liquid can be clear water, and can also be cleaning agent or nursing agent. The cleaning box is also provided with a liquid supplementing opening and a sealing cover, and after the cleaning liquid is used up, a user opens the sealing cover to add the cleaning liquid into the cleaning box through the liquid supplementing opening so as to reuse the cleaning liquid.

In some embodiments of the present invention, the cleaning device 200 may further include a drying device, a blowing device, and the like to dry the water absorbing member 4, so as to be used repeatedly, thereby preventing the user from manually drying the water absorbing member 4, freeing the user's hands, and improving the cleaning ability and efficiency.
